RELAY.

Application filed September 29, 1919.

To all whom t may concern:

Be it known that l, GEORGE R. GUiLD, a citizen of the United States, andan oiiicer of the United States Army, stationed at Baltimore, Maryland,have invented a certain new and useful improvement in Rei lays, of whichthe following is a full, clear, and lexact description, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification.

My invention relates generally to new and useful improvements in relaysand more particularly to a relay designed for use in connection with theelectrical circuits of practically. all forms of signaling systems andparticularly those systems utilized in connecting with railways for theguidance and control of trains.

The principal objects of my invention are, to generally improve upon andsim` plify the existing types of relays; to provide a relay having buttwo coils or solenoids; to combine with said relay relatively simpleconnections between thecrails of a section or blocko-f a railway track;to arrange in said connections visible signals to be observed by theengineer or train operator; and to provide a relay and signaling systemthat possesses superior advantages in point of simplicity, economy andgeneral eiliciency.

lilith .the foregoing and other objects in view, my invention consists`in certain novel features of construction and arrangement of parts,hereinafter more fully described and claimed, and illustrated in theaccompanying drawings, in whichliigure 1 is a diagrammatic view of arelay of my improved construction, the operating partsthereof being inneutral position and said relay being associated with the rails of arailway track and with signallamps ady jacent to said track.,

Fig. 2 is a vertical. section taken through the centerv of the. housingfor the relay and showing` the relative positions of the parts therein.

Figs. 3 and 4 are diagrammatic views of the relay, the armature andcontact carrying member of whichrelay are in shifted Serial No. 327,067.

positions and said views showing the active circuits in heavy lines.

Fig. 54 is a diagrammatic'view of my improved relay and showing itsconnections with a block or trackhaving turn-outs or side tracks.

Fig. 6 is a diagrammatic view illustrating the arrangement of myimproved relay in connection with astandard relay for open or closedcircuit signal circuits.

Fig. 7 is a diagrammatic view of my im# proved relay and showing itsconnection with a two-position combined turn-out and block signal.

Referring by numerals tothe accompany ing drawings, and particularly tothe construction illustrated in Figs. lto inclusive, 10 designates abox-shaped housing provided with a removable'top 11 and with ahorizontally disposed partition 13. Formed in this partition 13 is anaperture 14 and passing therethrough is a shaft, 15, the ends of whichare journaled in suitable bearings on the top 11 andon the bottom ofhousing 10.

Secured to. thelower portion of shaft 15 in any suitable manner andprojecting horizontally .therefrom is an armature 16, the free end ofwhich is disposed between the cores .of a pair of solenoid coils `17 and18. relatively light spiral spring'lfa has its inner ends secured toshaft 15 and its outerend secured to the underside of partition 13,which spring normally maintains said shaft and the armature 16 carriedthereby in neutral position between the cores of the solenoids asillustrated in Fig. r1. y

Positioned on shaft`1`5 abovethe partition 13 is a disk 19 of insulatingmaterial such as hard rubber or fiber and arranged in or near theperiphery thereof and immediately adjacent to each, other are metalcontact members 20 and 21. Arranged upon or adjacent to the periphery ofthe disk 19 and disposed substantiallyl at right angles to these contactmembers 2O and 21 is a pairiof Contact members 22 and 23. Arranged uponor adjacent to the periphery of kdisk 19 and preferably diametricallyopposite from the contact members `2O and 21 are threecontact members24, 25 and 26. l

wardly therefrom is a yielding contact meinn ber 27, preferablyresilient'metal, vthe free end otwhich is adapted to engage in any oneofthe contact members 24, and 26.

Aconductor' 34connects red lamp withl contact member 26; a conductor 35 connects greenlamp with contact member 25,; and a conductor 36 connects the yellowlamp 32'with contact member 24.

ductor 38. Aconductor 39 connects` contact member 22 with one end ot thecoil of solenoid 18 and the other end ot' this coil is connected tocontact member 21 Lby a conductor40. l Y

`Arranged on partition 13 is a flexible contact member 41, preferablyaresilient strip of which isl adapted to engage either one or both ofVthe contact members 22 and 23.'` Leading ronithis ycontaCUme/mber 41 toaibattery42 is a conductor V43 and leading from said battery .to thecontinuous or unbroken trackrail44 of a bloc-lr contact member 5() is aresilient contact meinber 52 that` is adapted to engage Contact member21, and ,leading from said contact member 52 to `rail section 47 is acon- Located A,adjacent to Contact member 48 is a resilient'contactmember 54 that is adapted to engage contact member 2G and leading fromsaidlcontafctmeml'iei' 54 to conductor V53 is Aa condiictor 55.

Under ynor-mal conditions, solenoid 17 is in series with that portion otthe block inV which rail-section 46 is located and solenoid 18 isinseries with that portion of the block l of which rail" section 47 formsa partl Thus both solenoidsor coils are atY all times'ready to beenergized from battery 42 by the trucks of a locomotive or car. oneitherportion ot' theblock. For instancea locomotive or car enteringtheA block in which rail `sectionl is located will cause traclcbattery42 tc dis-l chargecurrent throughthe circuit including conductor 43,contact member 41, contact is a resilient'- member 23, conductor 37,solenoid 17, conductor 38, contact member 20,-contact meinV ber 48,conductor 49, rail section 46 through the wheels and axles of the truck,as designated by X, Fig.v 3, thence through ,continu Vons rail 44 andfrom thencethrough conductor 45 back to battery. V

:As this circuit is thus energized, solenoid 17 will attract armature16, thereby rotating sha-tt 15 and the disk 19 clockwise a shortdistance, and the parts will then assume the positions illustrated inFig. 3 with Contact member 24 in engagement with contact member 27,thereby closing the circuit in which yellow lamp 32 is located, and as aresult said yellow lamp will burn to give visible warning that there isa locomotive or car upon that portion of the ybloc-l;V in which railsection46 is located. i

lt will be understood that prior to the partial rotation of disk 19vasjust describe l,

or while the parts are in normal position,

as illustrated in Fig. 1, contact members 25, and 27 are engaged,thereby closing the circuit in which green Vlamp is located and saidgreen lamp burns to make a visible signal and indicate. that the blockwith Vwhich this'particular lamp and relay are associated is. clear orIopen. i

As the disl 19 is thus rotated 4clockwise Contact member 2OV will engageboth contact members 48 and 54, and contact member `21 will move out ofengagement with Contact member 52thusl putting both rail Vsections 46and 47 individually in circuitl with sole -noid 17 Vonly andcutting-'solenoid 18 entirely outset circuit. Y ,l v h As a result 'ofthe operations just described, the green lamp is lcut out ot "circu itand theV yellow lainpA cut into circuit, and

the latter willpcontinuevto burn during the passage yofthe locomotive orcar through the block notwithstanding the ,fact that, said locomotiveorcar crosses the break or opening between iail sections 46 and 47.

lnthe event that a locomotive or carentei sV the end ot that portion ofthe block in v-fl'iich rail section 47 is located, (see Fig. 1) the circiiit.V in whichsolenoid 18 is located will be closed with theresulttli at the tree end of armature 1G willbe'attracted by the coreolf saidY solenoid, thereby partially` rotating tl 1 e brings about: anengagement of the contact members 26 and 27,*thereby closing the-circuit in which red lamp 30 is locatedand as tained during the entirepassage 'ofthe loco Y motive or train through the block,.-

In'Fig. 5 I have shown the application of my improved relay toa turn-outorside track in a block. In this construction, disk 191l is carried byarmature 16a, the free end of the latter being disposed between theinner ends of coils 17a and 18a. Carried by disk 19 is a pair of contactmembers 60 and 61 and said diskalso carryinga second pair of contactmembers 62 and 63.v f

Adapted to engage with either contact member 60 or 61 is a stationarycontact member 64 and leading therefrom to a battery 65 is a conductor66. Leading from Vthe other side of this battery to a red lamp 67 and agreen lamp 68 is a conductor 69, andV leading from red lamp 67 tocontact member 61 is a conductor 70. Leading from green lama 68 toContact member 60 is a conductor l71. Leading from contact members 62 tocoil 17a is a conductor 72, and leading from said coil to rail sectionWis a conductor 73. A stationary contact member 74 is adapted to engageeither orboth ofthe contacts 62 and 63 and leading from said contactmember`74 to a track battery 75 is a conductor 76. Leading from thetrack battery 75 to a rail section S is a conductor 77. Leadingfromcontact member 68 to coil 18al is a conductor 78, and leading from saidlast mentioned coil to a rail section P is a conductor 79.V l LocatedAat the opposite end of the block and adjacent to the turn-out railsections M and J are red and green lamps'80 and 81 respectively, andleading thereto from the 'battery 82 is a conductor 83. Leading fromthese lamps to contact members 84 and 85 are conductors `86 and 87,respectively, and adapted to engage the contact membersA 84 and 85 isthe end of a spring-held armature 88 that is connected tobattery 82. v

A relay 89 is arranged in position 4,to attract armature 88, said relaybeing connected to rail section M by a conductory 90 and to Irailsection Pby a conductor 91. Where Ait is desired to provide a turn-outSignal without interfering with the block signaling system, la conductoras shown by 92, Fig. 7. connects solenoid 18a with relay 89 and whenthis construction is carried out, it will be understood that theconductors 79 and 91 are eliminated. ln other words, for the blocksignaling system, the conductors 79 and 91 are provided,'but for theturn-out Signaling system, these conductors are eliminated, and aconductor such as 92 is installed.

Referring toFig. 7 and assuming that the relay is beingutilized in aturn-out signalying system' and'fthat `a :locomotive or jcar isegeasv18a and conductor 92.

'has entered that portion of the block in enters the' block first willcause battery to ydischan'ge current through conductor `76,

contacts 74 and'62, conductor 72, coil 17, conductor 73, rail section W,wheels and axles of the truck onthe rails W andH, and from the railsection H through a part of rail S and from thence through conductor 77to battery.

rlhus coil 17L will be energized which attracts armature 16,consequently moving disk 19 clockwise. When the disk has been thusmoved, the contacts 74 and 62 are still in engagement, but contacts 63and 74 are out-of engagement.` Consequently as long as the car is on thesectionof track in which rails H and W are located, coil 18Irl cannotget current, and consequently there can be Ano current How throughconductor 92 and the carl or locomotive on the section of the trackincluding rails M and J cannot affect or move the disk of the relay. w

When the disk of the relay isin neutral position, contacts 61 and 64 arein engagement and consequently red lamp 67 is receiving current frombattery 65 and is burning but upon the clockwise movement of disk 19a,contacts 6l and 64 are disengaged and contacts 60 and 64engaged, therebycutting out the circuit in which red lamp is located andl cutting inthev circuit in which the green lamp is located. Consequently it ispossible for the locomotive or car on the portion of the block includingrails H and W to effect a turning movement of the disk 19a clockwise,and the redlamp will be eX- tinguished and fthe `green lamp will belighted and at the same time the conditions will be such that thelocomotive or train on'the opposite end of the block or that portionincluding the rails M and J cannot get current from battery through coilHence the car or locomotive upon rail sections H and l/V and which wasthe first to enter the block cuts out its red signal lamp 67 `and causesits greensignall lamp 68 to burn and therefore the engineer ofsaid'locomotive or train may enter and pass through the block withsafety. Had the car or locomotive at the end of the block lincludingrail sections M and J entered the block first, then the disk of therelaywould be turned counter clockwise by the action of coil 18"L onarmature 16L and in suohevent battery 75 discharges current throughvrconductor 76, 'contacts 74 and 63 (contacts 74 and 62 beingdisengaged), conductor 78, coil 18, conductor 92, relaycoilf89,jconductor 90, rail section M iso , through the wheels and axlesof the truck finaintains the circuit in which:A the redlamp at the-lefthand end of the block is located andthusprevents a car .orlocomotive enter- V ing this flefthand end of the block from actuatingthe relay and cutting out its red signal and cuttingi'n thek greensignal. A

.Referring to Fig.15 and assuming a car to haveV entered. the lefthandend of, the blocker that portion including the rails H andNV,suchcantheblock being clear, cuts out the circuit in which the red lampis `located and'cuts in the circuit in which the greenlam'p is locatedand with such circuit the car may enterl vand pass through the blockduring which time or while the green lamp is burning the green lamp 81atthe opposite end ofthe block cannot (due to the position of the disk aspreviously described) receive current and burn. As the.

forward trucks of the car pass onto the rail section P, the rear truckswill maintain. the

green lsignaland such signal will be maintained as long as anyportion ofthe car or train is upon the `rail sections H andrVV.

Assuming a car to have entered the block with .no portion of the lcaronrail section lll, then the disk will immediately return to Inormalposition Vand then move counter clockwise by the energized coil V18awhich -attractsarmaturelt As a resulticurrent from battery passesthrough conductor 76,V contacts .711`and 63, conductor 78, coil 18,conductor 79, rail section P, through the wheels and axles yofthe truckto rail section S, from thence through conductor 17 `tobattery 75. 1 i

Thus the presence of a car on that portion `of the block including railsP- and Sfenergizes coil 18L` and although `relay# coilV 89 is,ininultiple with the car on the rails P `and S, in case there is a caronthat portion ofthe track including rails M and J, coil 89 ,cannot beenergized due to the :fact that the car on the rails P and S shunts saidcoil Aout of circuit. Therefore,.a car. entering the .lefthand endof-theeblock Vcauses thered ysignal lamps at both ends ofthe block toburn and preventing a car enteringeither end of the block from cuttingout. the red signal lamps and-cuttingin the greenilamps. Assuming that acarentersfthe end -of the block in which rails and J are'V located andthat the block isclear, then current will be discharged from battery 7'through'conductor 76, contacts 74, 63, "conductor 78, coil 18@` (henceturning the disk counter 4clockwise; thereby cutting the greenla'mpV atthe lefthand-end of the blocko'ut ofcircuit), conductor 7 9,rail P,conductor 91, relay coil 89 (which attracts Aarmature 88 and closes Vthecircuitito green lamp .81) ,n conductor 90,

' forming its intended functions.-

raiLM, crossthe wheels and axles ofthe truck to rail J Ithrough rail SAand conductor 77 to battery. Therefore, this vcar cuts out :theredsignallamp 8O andcomes into circuit with the green lamp 81, andprevents the` green signal lamp vat theopposite end .of the block fromburning.` As? the car passes froml rail YM onto lrai-l P, the; vforwardtrucks establish circuit between; Vrails P and S while the rear trucks,maintain the circuit between rails M andllrwith theresultthat coil 18Ldoes not Vreleasearmature P eliminated or disconnected.
